Reclaimed water is highly required for environmental sustainability and to meet sustainable development goals (SDGs). Chemical processes are frequently associated with highly hazardous and toxic by-products, like nitrosamines, trihalomethanes, haloaldehydes, haloketones, and haloacetic acids. In this context, we aim to summarize the formation of various commonly produced disinfection by-products (DBPs) during wastewater treatment and their treatment approaches. Owing to DBPs formation, we discussed permissible limits, concentrations in various water systems reported globally, and their consequences on humans. While most reviews focus on DBPs detection methods, this review discusses factors affecting DBPs formation and critically reviews various remediation approaches, such as adsorption, reverse osmosis, nano/micro-filtration, UV treatment, ozonation, and advanced oxidation process. However, research in the detection of hazardous DBPs and their removal is quite at an early and initial stage, and therefore, numerous advancements are required prior to scale-up at commercial level. DBPs abatement in wastewater treatment approach should be considered. This review provides the baseline for optimizing DBPs formation and advancements in the remediation process, efficiently reducing their production and providing safe, clean drinking water. Future studies should focus on a more efficient and rigorous understanding of DBPs properties and degradation of hazardous pollutants using low-cost techniques in wastewater treatment.
再生水对于环境可持续性和实现可持续发展目标(SDGs)非常重要。化学过程通常会产生高度危险和有毒的副产品,如亚硝胺、三卤甲烷、卤代醛、卤代酮和卤代乙酸。在这种情况下,我们旨在总结废水处理过程中各种常见的消毒副产物(DBPs)的形成及其处理方法。由于 DBPs 的形成,我们讨论了允许的限度、全球各水系统中报告的浓度以及它们对人类的影响。虽然大多数评论都集中在 DBPs 的检测方法上,但本评论讨论了影响 DBPs 形成的因素,并批判性地回顾了各种修复方法,如吸附、反渗透、纳滤/微滤、UV 处理、臭氧氧化和高级氧化工艺。然而,对危险 DBPs 的检测及其去除的研究还处于早期和初始阶段,因此,在商业规模扩大之前,还需要进行大量的改进。应该考虑在废水处理方法中减少 DBPs。本综述为优化 DBPs 形成和修复过程的改进提供了基础,从而有效减少其产生,提供安全、清洁的饮用水。未来的研究应侧重于更高效和严格地了解 DBPs 的特性以及使用低成本技术在废水处理中对有害污染物的降解。
